The Box One cassette brings together all the virtues of the Prime 9 philosophy and distills them into what we feel is our most defining product to date. A unique machined all-steel unibody lattice and alloy support disc have netted us a high-performing, simple, durable and lightweight cassette. We could have exploited a sub 300g weight with an alloy cog but chose to stay true to our value proposition.
